Racing authorities want rogue trainers who use live animals to train greyhounds kicked out of the sport for good.
Seven Queensland trainers under investigation for live baiting face being warned off any race track, including horse racing and trots, and banned from the industry for life.
Racing Queensland chairman Kevin Dixon said the trainers had seven days to show why they should not be prevented from visiting any racecourse, placing a bet and training, preparing or owning a registered racing animal.
One of the trainers subject to both suspension and a show cause notice, Tom Noble, said he expected a harsh punishment.
"Well, I'll get life. They won't let me race a dog again," he told the Nine Network.
"It's a big industry, greyhound racing, I can't see it folding up, but it's not going to do it any good."
Another trainer, Reg Kay, will be removed from the Queensland Greyhound Hall of Fame.
A further six Queensland trainers are suspended and their greyhounds have been barred from competing pending an investigation.
Thirty trainers in all have been suspended in Victoria, NSW and Queensland, out of 70 people implicated in using live animals to `blood' dogs.
Greyhound Racing Victoria's integrity, racing and welfare general manager Glen Canty said the case was unprecedented and the complex investigation would take time.
"We have immediately suspended all the individuals identified from evidence provided to us and will work hard to identify others as more information comes to hand," Mr Canty said.
"It is our intention, as well as the demand of most people in the sport, to drive these rogue elements out."
Victorian authorities have stopped greyhounds trained or owned by 10 suspended trainers, all linked to a private training facility in Tooradin, from racing while the allegations are investigated.
The move also stops the dogs racing if they had been transferred to another registered person.
GRV said it was unable to confirm whose registrations were suspended on legal advice, amid reports its former integrity and racing operations manager Bob Smith was among those caught up in the scandal.
Seven NSW trainers have been stood down pending investigations.
RSPCA Australia CEO Heather Neil said hundreds of dogs were now potentially at risk of being put down after being suspended from racing.
The RSPCA wants an independent overhaul of the industry's regulation.
Greyhounds Australasia CEO Scott Parker said the industry controlling bodies were backing government reviews and setting up independent taskforces and would make any changes they recommended.
"If that means a change to their integrity role, if that's deemed in the best interests of restoring public confidence to the industry, then the industry will need to accept that and we'll almost certainly accept that willingly," he told AAP.
